Referring to FIG. 1 and FIG. 2, while referring to FIG. 3 to FIG. 8 at the same time. FIG. 3 is a lateral view diagram illustrating the first embodiment of the present invention where the electronic apparatus is fixed to the support base. FIG. 4 is a lateral view diagram to illustrate that the electronic apparatus of the first embodiment of the present invention is not fixed to the support base and springs upwardly. FIG. 5 is a lateral view diagram illustrating that the angle between the display device and the support base of the present invention is a first angle. FIG. 6 is a lateral view diagram illustrating that the angle between the display device and the support base of the present invention is a second angle. FIG. 7 is a lateral view diagram illustrating that the angle between the display device and the support base of the present invention is a third angle. FIG. 8 is a lateral view diagram illustrating that the angle between the display device and the support base of the present invention is a fourth angle.
As illustrated in FIG. 1, FIG. 2, and FIG. 3, in the first embodiment of the present invention, when the display device 91 is placed on the support base 92 in a lying state as shown in FIG. 3, the supporting apparatus 1 is held within the holding groove 923 of the support base 92 and the hook 9241 is hooked within the buttonhole 911 of the display device 91 so as to fix the display device 91 to the support base 92; in this state, the electronic apparatus 90 can be used as a tablet computer. When a user moves the switch element 9242 in the direction indicated by the arrow in FIG. 3, the switch element 9242 controls the hook 9241 to be moved such that the hook 9241 leaves the buttonhole 911. When the hook 9241 leaves the buttonhole 911, the second support element 20 of the supporting apparatus 1 rises with rotation relative to the support base 91 via the elastic force provided by the first elastic component 60a. With support by the supporting apparatus 1, the display device 91 can move slightly and automatically to the predetermined position shown in FIG. 4, such that the user may directly slide or move the display device 91 after unfixing the fixed status between the display device 91 and the support base 92. Therefore, the user does not need to separate the display device 91 and the support base 92 manually.
As illustrated in FIG. 1, FIG. 4, and FIG. 5, when the display device 91 is supported and moved to the predetermined position, the user may move the display device 91 backward (in the direction of the arrow F1 shown in FIG. 4), such that the display device 91 slides backward along the convex rails 922. As it slides, the display device 91 gradually rises upward in the direction of F2 illustrated in FIG. 4. Finally, when the linkage levers 94 connected to the display device 91 move to the final end of the sliding grooves 921, the display device 91 can lean on the support base with a side of the display device 91 such that the display device 91 is placed on the support base upright or slopingly with the support of the supporting apparatus 1; in this state, the electronic apparatus 90 can be used as a laptop computer.
As illustrated in FIG. 2, FIG. 5, and FIG. 6, when the user presses downward in the direction of the arrow illustrated in FIG. 5, the first support element 10 of the supporting apparatus 1 moves downward along the pressing direction. Because the length of the supporting apparatus 1 is changed, the clamping angle between the display device 91 and the support base 92 is changed accordingly, such that the electronic apparatus 90 appears as illustrated in FIG. 6. Thus it may provide the user with a different viewing angle.
As illustrated in FIG. 2 and FIG. 7, the display device 91 of the electronic apparatus 90 can also be moved forward to lean on the different locations of the support base 92 by the concave groove 9221 of the convex rail 922 to allow the electronic apparatus 95 to form more viewing angles. Moreover, when the display device 91 leans on any location of the support base 92, the viewing angle of the electronic apparatus 90 can be further changed as illustrated in FIG. 8 by adjusting the length of the supporting apparatus 1. Therefore, the clamping angle between the display device 91 and the support base 92 of the present invention not only can be changed by moving the location where the display device 91 leans upon but also by adjusting the length of the supporting apparatus 1. Thus, more viewing angles are provided with such a design.
It is to be noted that although only one concave groove 9221 is disposed in each convex rail 922 in the embodiments of the present invention, such an arrangement should not be construed as a limitation of the present invention. More concave grooves 9221 can be disposed on different positions on the convex rail 922 to provide more fixing locations where the display device 91 leans thereon so as to provide more variation in the clamping angle between the display device 91 and the support base 92 by more changes of positions where the display device 91 leans thereon. It is also to be noted that although the supporting apparatus 1 uses the elastic force of the elastic components 60a, 60b, and 60c as the source of supporting force, such a design should not be construed to limit the present invention. The supporting apparatus 1 of the present invention can also use axial levers with high friction coefficients. In this case, friction force between the axial levers and the support elements or the connecting elements can be used as source of supporting force. When each connecting element is rotated with multiple angles relative to each of the support element via the axial levers, the length of the supporting apparatus 1 can be adjusted within the maximum extendible range so that the clamping angle between the display device 91 and the support base 92 can have even more variations, even if the display device 91 is located on the same location of the support base 92.
Finally, please refer to FIG. 2, FIG. 6, and FIG. 9, wherein FIG. 9 is a back view diagram of a second embodiment according to the present invention.
As illustrated in FIG. 2 and FIG. 6, when the supporting apparatus 1 supports the display device 91 as illustrated in FIG. 6, because the display device 91 is supported only with the elastic force of the elastic components 60a, 60b, and 60c, the display device 91 will move backward in the direction of the arrow F4 in FIG. 6 if the force generated by the pressing of the user is greater than the elastic force provided by the elastic components 60a, 60b, and 60c. Thus the display device 91 could not be operated steady. To eliminate such a deficiency, as illustrated in FIG. 6 and FIG. 9 in the second embodiment of the present invention, two sides of the second support element 20 of the supporting apparatus 1 are extended and formed as two support portions 22 (the other side is not shown because of the viewing angle). With such a design, when the supporting apparatus 1 supports the display device 91 in the manner of FIG. 6, the support portions 22 can be used to support the display device 91 such that the display device 91 not only can be supported by the elastic force provided the elastic components 60a, 60b, and 60c but also by the reactive force provided by the support portions 22. Therefore, the display device 91 can also be operated robustly in this state to cure the aforementioned problem.
It is also to be noted that for clarity and simplicity, only preferred embodiments are explained, and not all possible variations and combinations are listed. Persons of ordinary skill in the art, however, can understand that not every component mentioned above is necessary. Moreover, to implement the present invention, other conventional components can be added in more detail. Each component can be ignored or modified, and additional components may exist between two existing components. For example, when the display device 91 or the support base 92 has an axial lever, the first axial lever 30a or the third axial lever 30c of the supporting apparatus 1 can be omitted.
The above descriptions of the embodiments of the present invention have been presented only for purposes of illustration and description. They are not intended to be exhaustive or to limit the present invention to the forms disclosed. Accordingly, many modifications and variations will be apparent to practitioners skilled in the art. Additionally, the above disclosure is not intended to limit the present invention. The scope of the present invention is defined by the appended claims.
